MIN/MAX 12 Hold measured value 13 Functions Function/Application The anemometer is used to measure air × ow rates, volumetric × ow rates and wind speeds. Integrated sensors constantly register the ambient temperature, relative humidity and calculate the dew point temperature. The USB interface additionally permits realtime logging on a PC. Read the operating instructions and the enclosed brochure „Guarantee and additional notices“ completely. Follow the instructions they contain. Safely keep these documents for future reference.

2 sec 2 sec Einlegen der Batterien When switched on, the ambient temperature and relative humidity are permanently shown on the display. The dew point or wet-bulb tem- perature can also be set in place of the ambient temperature. Change between the different values by pressing and holding the „DP/WP“ button. You can set the units °C/°F by pressing and holding the „UNIT“ button. DeactivatedActivated AUTO-Off (20 min.) Room climate Open battery compartment and insert batteries correspon- ding to installation symbols. Ensure correct polarity.

After switching on by pressing the „MODE“ button, activate the „VEL“ function. Press the „UNIT“ button repeatedly to change the units: m/s (metres per second), km/h (kilometres per hour), mil/h (miles per hour), ft/m (feet per minute), ft/s (feet per second), knots. Press the „MAX/MIN“ button to display the highest and/or lowest value during a measure- ment. As its name suggests, the „HOLD“ but- ton enables you to hold the current measured value. Wind speed Please refer to the following instructions for use when determining wind speed or volumetric ƃ ow rate: – Position the device parallel to the × ow source – Place the device as close as possible to the × ow source – Use the MAX function to determine the position with the strongest air × ow – Avoid direct sunlight during measurement GB11 AirflowTest-Master

The outlet area of the × ow source must Ö rst be deÖ ned before determining volumetric × ow. After switching on by pressing the „MODE“ button, activate the function for measuring volumetric × ow until „AREA“ appears on the display. The Ö rst number begins to × ash. Use the „“ (+) and „SET“ (change decimal place) buttons to enter the determined area. The area can be set both in square metres (m²) as well as in square feet (ft²). The end of the input is signalled by a double beep. Activate the „FLOW“ function by pressing the „MODE“ button. After selecting the correspon- ding unit – CMM (cubic metres per minute), CFM (cubic feet per minute) and CMS (cubic metres per second) – press the „UNIT“ button to determine the volumetric × ow based on the set area. Volumetric flow The „MODE“, „UNIT“ and „MIN/MAX“ functions are deactivated while the „HOLD“ function is activated. These functions are available again after pressing the „HOLD“ button once more.

Measured values can be transferred to a PC in realtime via the integrated USB interface. The values can then be stored and documen- ted using the supplied software. First install the software and the corresponding drivers from the CD to the terminal unit. Follow the instructions for the installation routine. Once you have successfully installed the software, connect the measuring instrument to the PC and set up a USB connection. Start the software and activate the USB func- tion by pressing and holding the „USB“ but- ton. The software now shows the measured values both in numerical as well as in graphic form. For further information on how to use the software, refer to the Help function that con- tains a detailed description of the functions. USB transfer The MAX function is activated by pressing the „MAX/MIN“ button. The measured value currently displayed corresponds to the largest measured value. Press the „MAX/MIN“ button again to activate the MIN function and show the smallest measured value. To deactivate „MAX/MIN“, press the button again until the value is no longer shown on the display. Press the „HOLD“ button to hold the current measured value on the display. Press the button again to deactivate this function.
